O-rings are mechanical gaskets with a round cross section. They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers. Some of our common types of O-ring materials include PTFE, Nitrile (Buna) , Neoprene , EPDM Rubber and Fluorocarbon (Viton) . Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.
Ace Seal provides O-rings in standard and metric sizes and different material options to meet your application requirements. Our industry standard O-ring material sizes vary depending on the type of O-ring product selected. Custom sizes, profiles, materials and durometers are also available upon request.
Ace Seal offers a broad range of O-ring materials in different colors and sizes to meet your sealing application requirements. We provide O-rings for industries ranging from oil and gas to aerospace and offer both standard and custom options. Learn more about our various types of O-ring material below or contact us to discuss customization options.

There are numerous types of O-ring materials available and each offers different features and benefits. Some materials perform well in chemical or high heat applications where others may deteriorate under harsh operating conditions. Even the specific type of oils or chemicals being used in your application determine O-ring material compatibility. Abrasion and tear resistance may also be of importance, especially in dynamic applications or when abrasive substances are involved.
Primary considerations for O-ring material selection include chemical compatibility, application temperature compatibility, sealing pressure, durometer, size and cost. Depending on the application, factors such as electrical properties, dynamic resistance, tear resistance and ozone resistance should also be considered. Taking all these parameters into consideration will help you determine which O-ring material choice is best suited for your application.
